设置response头信息禁止缓存

java代码中可通过如下代码设置

response.setHeader("Pragma", "No-Cache");
response.setHeader("Cache-Control", "No-Cache");
response.setDateHeader("Expires", 0);

同理，nginx服务器上也可通过给nginx添加响应头，让html,css,js不缓存

nginx.conf

location / {

add_header Cache-Control no-cache;

add_header Pragma no-cache;

add_header Expires 0;

}
